Luggage contents recommendations and tracking

ABSTRACT

In an approach for suggesting an item to pack, a processor receives an indication that a user is packing a first item of luggage, wherein the indication includes information about a trip. A processor generates a packing list based on the information about the trip. A processor receives a request to link the first item of luggage and a second item of luggage for the trip. A processor links the first and second items of luggage such that contents of each item of luggage are jointly compared to the packing list. A processor receives, via a short-range point-to-point communication reader of the first item of luggage, a signal from a short-range point-to-point communication device operably affixed to a first item. A processor identifies the first item based on the signal. A processor determines that the first item is an item of the packing list.

Asdescribed herein is an approach to log items stored in luggage, providerecommendations of items to add and remove to luggage based oninformation about the trip and/or past preferences, and provide alertswhen issues have arisen that may result in lost or misplaced luggage.

The present invention will now be described in detail with reference tothe Figures.

FIG. 1 depicts a diagram of computing environment 100, in accordancewith one embodiment of the present invention. FIG. 1 provides only anillustration of one embodiment and does not imply any limitations withregard to the environments in which different embodiments may beimplemented.

In the depicted embodiment, computing environment 100 includes computingdevice luggage 120 and mobile device 180 interconnected over network110. Network 110 may be a local area network (LAN), a wire area network(WAN) such as the Internet, the public switched telephone network(PSTN), a Bluetooth® connection, any combination thereof, or anycombination of connections and protocols that will supportcommunications between computing device-luggage 120, mobile device 180,and, in some embodiments, other servers or computing devices (notshown), in accordance with embodiments of the invention. Network 110 mayinclude wired, wireless, or fiber optic connections. Computingenvironment 100 may include additional servers, computing devices,mobile devices, wireless communication devices (e.g., radio frequencyidentification (RFID) tags, near field communication (NFC) devices, orother devices not shown.

Computing device-luggage 120 may be a computing device affixed, orotherwise incorporated into an item of luggage (not shown). In general,computing device-luggage 120 may be any electronic device or computingsystem capable of receiving and sending data and communicating withmobile device 180 via network 110. In some embodiments, computingdevice-luggage 120 may be capable of communicating with other servers ormobile devices (not shown). In the depicted embodiment, computingdevice-luggage 120 includes RFID reader 130, list database 140, luggagecontents program 150, initial packing function 160, multiple luggageitems function 165, and return packing function 170. Computingdevice-luggage 120 may include components, as depicted and described infurther detail with respect to FIG. 5.

It should be noted that, as used herein, the term “luggage” is notmerely restricted to suitcases, but may include other types ofcontainers. For example, luggage may include backpacks, purses,briefcases, handbags, laptop cases, or any other type of container,satchel, or bag utilized to carry one or more items.

RFID reader 130 is an RFID tag reader. RFID reader 130 may include atransceiver for generating a radio frequency (RF) signal, as well as areader antenna coupled to the transceiver for transmitting the RFsignal. RFID reader 130 may be capable of receiving information storedto RFID tags. In some embodiments of the present invention, a user ormanufacturer may affix RFID tags to personal items and RFID reader 130may be designed to retrieve information from the RFID tags as they areplaced in the luggage item that contains RFID reader 130 and computingdevice-luggage 120 or, in some embodiments, upon the luggage item beingclosed.

It should be noted that while the depicted embodiment describes RFIDreader 130 and the use of RFID tags, other types of short-rangepoint-to-point communication technologies may be utilized; for example,near field communication (NFC), Bluetooth®, or other approaches.

In some embodiments, computing device-luggage 120 may further includecomponents to enable location tracking and or location proximity toother devices. For example, some embodiments of computing device-luggage120 may utilize Bluetooth® to enable computing device-luggage 120 toconnect to mobile device 180 or another item of luggage equipped withsimilar technology. Similarly, computing device-luggage may include aglobal positioning system (GPS) receiver to allow computingdevice-luggage 120 to receive GPS coordinate and locate the location ofthe item of luggage. Computing device-luggage 120 may also be equippedwith components that enable computing device-luggage 120 to connect to acellular network. In such embodiments, location may be determined bymultilateration techniques, or GPS coordinates may be relayed to, forexample, mobile device 180.

Luggage contents program 150 operates to log the contents of one or moreitems of luggage, provide recommendations as to items that should beadded or removed from luggage, and to generate alerts to be sent to auser via user interface (UI) 185 of mobile device 180. In the depictedembodiment, luggage contents program 150 includes initial packingfunction 160, multiple luggage items function 165, and return packingfunction 170.

Initial packing function 160 operates to monitor and log items placed ina luggage item and provide recommendations of items to add or removefrom the luggage item. In some embodiments, such recommendations arebased upon received information about the current trip such as, forexample, destination, purpose of trip (e.g., business, leisure),duration of the trip, itinerary information (e.g., planned activities,hotel reservations, travel arrangements), or other information. In someembodiments, initial packing function 160 utilizes the receivedinformation to generate recommendations based on accessing externalservers or computing devices for information including, for example,hotel amenity information, weather-related information, airlineguidelines, or other types of information.

Multiple luggage items function 165 operates to manage multiple items ofluggage and cause initial packing function 160 and return packingfunction 170 to monitor the contents of multiple items of luggage. Inaddition, some embodiments of multiple luggage items function 165 maycause an alert to be sent to a user via, for example, UI 185 of mobiledevice 180 if any of the multiple items of luggage are geographicallyseparated.

Return packing function 170 is similar to initial packing function 160,albeit is designed for a return trip or subsequent stop on a multi-stoptrip. Return packing function 170 operates to monitor and log items inluggage based on the log of items created during packing as initialpacking function 160 was executing. In some embodiments, return packingfunction 170 allows a user to add additional items; for example, itemsobtained during a trip. Return packing function 170 may generate analert upon determining that one or more items is missing, in order toprevent a user from leaving personal items at the destination of theirtrip.

List database 140 may be a repository that may be written to and read byluggage contents program 150, initial packing function 160, multipleluggage items function 165, and/or return packing function 170. Itemlists may be stored to list database 140. Each item list may include aset of items that are recommended and/or a set of items that are notrecommended to be packed in the luggage item based upon a variety offactors. For example, a user may utilize mobile device 180 and UI 185 tocreate a list for a particular trip. In some embodiments, list database140 contains lists that were created by a function of luggage contentsprogram 150 based on historical travelling information including, forexample, previously brought items. In some embodiments, multiple listsmay exist for multiple types of trips (e.g., vacation, business,warm-climate, cold-climate). In some embodiments, travel lists may beadjusted based on a specified duration of the trip. A variety of listsmay be entered, and received information about a trip may enable initialpacking function 160 to select a list. In some embodiments, item logsmay be stored to list database 140. Item logs may indicate a set of oneor more items identified as being placed in the item of luggage byinitial packing function 160.

Mobile device 180 may be a desktop computer, laptop computer, tabletcomputer, or smart phone. In general, mobile device 180 can be anyelectronic device or computing system capable of sending a receivingdata, and communicating with computing device-luggage via network 110.Mobile device 180 includes UI 185. Mobile device 180 may includecomponents, as depicted and described in further detail with respect toFIG. 3.

UI 185 operates on mobile device 180 to act as an interface to luggagecontents program 150, initial packing function 160, multiple luggageitems function 165, and/or return packing function 170. UI 185 maydisplay data received from luggage contents program 150, initial packingfunction 160, multiple luggage items function 165, and/or return packingfunction 170 and send received input to luggage contents program 150,initial packing function 160, multiple luggage items function 165,and/or return packing function 170.

It should be noted that while, in the described embodiment, informationis input to and communicated to a user via UI 185 of mobile device 180,computing device-luggage 120 may, in some embodiments, include a meansto provide input and receive information. For example, in someembodiments, computing device-luggage 120 may have a touch screen orother device capable of allowing a user to interact with luggagecontents program 150, initial packing function 160, multiple luggageitems function 165, and/or return packing function 170.

FIG. 2 depicts a flowchart 200 of the steps of initial packing function160, a function of luggage contents program 150, executing withincomputing environment 100 of FIG. 1, for monitoring items placed intothe item of luggage and providing recommendations of items to add orremove from the item of luggage, in accordance with some embodiments ofthe present invention.

In one embodiment, initially, items to be placed in an item of luggageare equipped with RFID tags or another short-range point-to-pointcommunication technology device. In some instances, a user intending totravel affixes the items with RFID tags. In other instances, amanufacturer of the item may affix respective items with RFID tags. Ingeneral, the RFID tag or other short-range point-to-point communicationtechnology device may contain information indicating what the item is,and may be capable of transferring that information to luggage contentsprogram 150 via, for example, RFID reader 130.

Further, in some embodiments, a user may have created one or morepredefined lists. For example, a user may have particular medication,toiletries, or other sets of items that are regularly taken on trips. Auser may specify a first set of items that should be taken on businesstrips and a different set of items that should be taken on leisuretrips. A variety of lists of items may be created by the user and maydepend on a variety of aspects about the trip. In some embodiments,initial packing function 160 creates a list based on previouslymonitored sets of items included in past trips. Each list may includeone or more annotations indicating circumstances around which the listshould be used. For example, a list for business travel may be annotatedto indicate that the list for business travel should be used only whenthe user inputs that the trip is a business trip. Other similarannotations may be added based on a variety of factors relevant totrips.

In step 210, initial packing function 160 receives information about atrip. A user at mobile device 180 may utilize UI 185 to inputinformation about the trip in order to assist initial packing function160 in retrieving an applicable list and identifying items that shouldbe recommended to the user for packing. Information the user may enterabout the trip may include, for example, the type of trip (e.g.,business, vacation), the expected climate of the destination (e.g., hot,cold), the duration of the trip, or other information. Alternatively, orin addition to, a user may input itinerary information such as hotelreservations, travel reservations, planned activities, or otherinformation.

In step 220, initial packing function 160 generates a list of one ormore items. In some embodiments, a user may at mobile device 180 mayutilize UI 185 to select a list for the trip. In other embodiments,initial packing function 160 may compare received information about thetrip (see step 210) to annotations associated with previously storedlists located on list database 140. In such an embodiment, upon matchingthe received information about the trip with one or more annotationsassociated with previously stored lists, initial packing function 160may select one or more applicable lists. In another embodiment, initialpacking function 160 may utilize received information to retrieveinformation about the trip form external servers or computing devicesand create a list. For example, while a user may not have specified thata destination is going to be cold, hot, wet, or dry, initial packingfunction 160 may use a received destination address, retrieve weatherinformation from an external server or computing device, and utilizethat weather information to determine whether attire to be packed shouldbe for warm or cold weather. Similarly, initial packing function 160 mayidentify shops located at or near various destination locations (e.g.,hotel, airport) where various items can be purchased. Initial packingfunction 160 may access external servers or websites to identify shopinventory, and goods or services that can be purchased at such anidentified shop. For example, initial packing function 160 may identifythat a user has a destination near a beach, that the user is taking aplane, that the airline has guidelines against allowing liquids onplanes, and that there is a drug store near the destination hotel thatsells sunblock. As such, in that example, initial packing function 160may not include sunblock on the list, and may recommend (see step 250)that the user remove sunblock from the item of luggage if the userattempts to pack sunblock. A variety of other similar examples areenvisioned by embodiments of the present invention.

In some embodiments, initial packing function 160 may utilize past tripsto generate a list of one or more items, rather than base suchinformation merely on lists inserted by a user. For example, initialpacking function 160 may identify trends of items taken on particulartypes of trips (e.g., business trips to cold-weather climates, trips towarm-weather climates located near a body of water, trips where the modeof transportation includes an airplane). Upon identifying such a trend,initial packing function 160 may adjust particular lists. In someembodiments, rather than adjusting the lists, initial packing function160 may send a request to a user via UI 185 of mobile device 180,informing the user of the item initial packing function 160 hasidentified, and lists or annotations initial packing function 160 hasidentified to associate with the item.

In step 230, initial packing function 160 monitors and logs items placedin the item of luggage. In some embodiments, initial packing function160 monitors and logs the items placed in the item of luggage inreal-time as the user places items in the item of luggage. In otherembodiments, initial packing function 160 monitors and logs the itemsplaced in the item of luggage upon the user closing the luggage, or uponthe user selecting an option via UI 185 of mobile device 180 indicatingthat the item of luggage is packed and ready for the logging of items.The log of items may be stored to list database 140 along with thereceived information about the trip, and whether the trip is inprogress, or has been completed (and thus, is a past trip). In someinstances, a user may place an item that is not affixed with an RFID tagor other type of short-range point-to-point communication technologydevice. In such an instance, UI 185 of mobile device 180 may allow for auser to indicate that the item has been placed in the item of luggage.In some embodiments, since initial packing function 160 is unable toactively monitor whether such an item is included within the item ofluggage, initial packing function 160 may cause return packing function170 to generate a reminder (e.g., a push notification, textnotification) and cause the reminder to be sent to mobile device 180, inorder to assist in preventing a user from forgetting the item during thereturn trip.

In decision 240, initial packing function 160 determines whether itemsfrom the generated list (see step 220) have been placed in the item ofluggage. In some embodiments, initial packing function 160 may furtherdetermine whether items have been placed in the item of luggage that arenot located on the generated list. Initial packing function 160 maydetermine whether items from the generated list (or other items) havebeen placed in the item of luggage based on accessing the created log ofitems placed in the item of luggage (see step 230) and comparing the logto the generated list (see step 220). If initial packing function 160determines that the items placed in the item of luggage correspond tothe items from the generated list (decision 240, yes branch), thefunction is complete. If initial packing function 160 determines thatthe items placed in the item of luggage to not correspond to the itemsfrom the generated list (e.g., there are missing items from the listand/or there are items in excess of the list) (decision 240, no branch),initial packing function 160 generates a recommendation of items to beadded to and/or removed from the item of luggage.

In step 250, initial packing function 160 generates a recommendation ofitems to be added to and/or removed from the item of luggage, based onthe determined missing items or items in excess as compared to thegenerated list. Initial packing function 160 may cause therecommendation to be sent to mobile device 180 for access by a user viaUI 185. The recommendation may indicate one or more items initialpacking function 160 recommends the user add to the item of luggage,and/or one or more items initial packing function 160 recommends theuser remove from the item of luggage. In some embodiments, initialpacking function 160 also generates a reason why such a recommendationwas made. For example, initial packing function 160 may recommendremoving an item because the item is frequently packed but has beeninfrequently, or never, removed from the item of luggage during previoustrips (e.g., during a preselected number of trips). Similarly, initialpacking function 160 may recommend removing an item because initialpacking function 160 has identified a location nearby the destinationwhere the item can be purchased, and recommends purchasing the itemrather than packing. Such a determination may be made when generatingthe list (see step 220) and may be based on a variety of factorsdescribed above. Additionally, initial packing function 160 may takecost into consideration via, for example, airline guidelines, and mayrecognize that a particular item may cause the item of luggage to exceedan acceptable weight or require a larger item of luggage. Initialpacking function may make such a determination based on the dimensionsof the item of luggage, known weights of particular items (e.g.,gathered online or based on information stored to the RFID tagsassociated with each item), or sensor data. In some embodiments, a usermay prefer to only receive recommendations if the user has forgotten anitem, or if items are lacking, rather than if there are additionalitems. In such an embodiment, if the items of the generated list arepresent in the item of luggage, initial packing function 160 may foregogenerating a recommendation to remove items from the item of luggage.

FIG. 3 depicts a flowchart 300 of the steps of multiple luggage itemsfunction 165, a function of luggage contents program 150, executingwithin computing environment 100 of FIG. 1, for linking two or moreitems of luggage and sending an alert if linked items of luggage areseparated, in accordance with some embodiments of the present invention.

In step 310, multiple luggage items function 165 receives a request tolink two or more items of luggage. A user may request to link two ormore items of luggage because they are taking multiple items of luggageon a trip. In some embodiments, a user may specify whether it isexpected that the items of luggage should remain, within a predeterminedthreshold distance, near one another. In other embodiments, this may notbe the case (e.g., if a user has a carry-on bag and a bag they areplanning on checking with an airline) and the user may specify that thetwo or more items of luggage, while linked, do not need to remain nearone another.

In step 320, multiple luggage items function 165 links two or more itemsof luggage by causing the logs to be merged for the two or more piecesof luggage, for the analysis performed by initial packing function 160and/or return packing function 170. While the logs need not bephysically merged, multiple luggage items function 165 causes initialpacking function 160 and/or return packing function 170 to aggregate thecontents of each of the two or more pieces of luggage when determiningwhether items are, or are not, present in the two or more items ofluggage. As such, if “item A” is originally packed in “suitcase A,” and“suitcase A” and “suitcase B” are linked, on the return trip, if “itemA” is packed in “suitcase B,” return packing function 170 will notdetermine that “item A” is missing (due to “item A” no longer being in“suitcase A”). Effectively, multiple luggage items function 165 causesthe combination of the two or more pieces of luggage that are linked tobe analyzed as if they are a single item of luggage.

In decision 330, in some embodiments, multiple luggage items function165 determines whether linked bags have been separated, beyond, oroutside of, a predetermined threshold distance. As described above, someembodiments of computing device-luggage 120 may be equipped withcomponents capable of identifying the location of computingdevice-luggage 120. For example, computing device-luggage 120 mayutilize a GPS receiver and cellular network to relay GPS coordinates tomobile device 180, another computing device-luggage, or anothercomputing device or server. Thus, multiple luggage items function 165may determine whether linked bags have been separated by comparing theGPS coordinates of computing device-luggage 120 to the GPS coordinatesof another linked item of luggage. In another embodiment, computingdevice-luggage 120 may be equipped with Bluetooth® and the two or morelinked items of luggage may maintain a Bluetooth® connection with oneanother. In such an embodiment, multiple luggage items function 165 mayconsider the two or more linked items of luggage separated if theBluetooth® connection is severed. If multiple luggage items function 165determines that the two or more items of luggage have not been separated(decision 330, no branch), the function is complete. However, it shouldbe noted that multiple luggage items function 165 may be configured toperiodically determine whether the two or more items of luggage have orhave not been separated. If multiple luggage items function 165determines that the two or more items of luggage have been separated,beyond a predetermined threshold distance (or based on, for example, asevered Bluetooth® connection) (decision 330, yes branch), multipleluggage items function 165 generates an alert (see step 340).

In step 340, multiple luggage items function 165 generate an alert. Thealert may indicate that an item of luggage linked to one or more otheritems of luggage is no longer with the one or more other items ofluggage. Such a situation may arise when, for example, a user forgets anitem of luggage in a hotel room. In some embodiments, multiple luggageitems function 165 causes the alert to be sent to mobile device 180 andaccessible to the user via UI 185. In some embodiments, the alert is apush notification or a text message to mobile device 180.

It should be noted that, as described above, the two or more items ofluggage may be identified as linked, but it may be indicated that thetwo or more items of luggage can be separated. In such a circumstance,multiple luggage items function 165 may forego determining whether thebags are separated and sending an alert and may merely cause initialpacking function 160 and return packing function 170 to log and trackitems stored in the linked two or more items of luggage appropriately.

FIG. 4 depicts a flowchart 200 of the steps of return packing function170, a function of luggage contents program 150, executing withincomputing environment 100 of FIG. 1, for logging items on a return trip,or additional leg of a trip, and generating alerts if previously loggeditems are no longer present, in accordance with an embodiment of thepresent invention.

In general return packing function 170 may initiate execution similarlyto when initial packing function 160 is executed. However, returnpacking function 170 executes after a trip has already been started, butis not yet complete. Thus, return packing function 170 may execute whenpacking an item of luggage for a return trip, or when packing for anadditional leg of a trip.

In step 410, return packing function 170 monitors and logs items storedin an item of luggage. This step is similar to step 230, as describedwith reference to initial packing function 160 (see FIG. 2).

In decision 420, return packing function 170 determines whether anyitems are missing from the item of luggage. Return packing function 170may determine that an item is missing from the item of luggage bycomparing the previously stored log (see initial packing function 160,FIG. 2) associated with the current trip to items monitored as beingpresently stored in the item of luggage. If return packing function 170determines that there are not missing items (decision 420, no branch),the function is complete. If return packing function 170 determines thatthere are missing items (decision 420, yes branch), return packingfunction 170 generates an alert (see step 430).

In step 430, return packing function 170 generates an alert. The alertmay indicate the one or more missing items identified by return packingfunction 170 (see decision 420) and return packing function 170 maycause the alert to be sent to mobile device 180 for access via UI 185.In some embodiments the alert may take the form of a push notificationor text message. In some embodiments, UI 185 may provide an interfacefor allowing the user to choose to ignore or dismiss an alert. Forexample, return packing function 170 may issue an alert that one or morearticles of clothing are missing from the luggage, and the user may bewearing the articles of clothing. In such an example, the user may wantto dismiss the alert. In another example, the item may be something thathas since been thrown away, or was gifted or sold to another person. Itis recognized that there may be a variety of reasons why an item may nolonger be present in an item of luggage and that a user may wish todismiss an alert.

In some embodiments, return packing function 170 may additionally allowa user to add items to the previously stored log utilizing UI 185 ofmobile device 180. Such a feature may be desired to account for, forexample, items purchased while travelling on the trip. Upon adding suchan item to the previously stored log, return packing function 170 willtreat the item similarly to items originally included on the originalpreviously stored log.

FIG. 5 depicts a block diagram 500 of components of computingdevice-luggage 120, in accordance with an illustrative embodiment of thepresent invention. It should be appreciated that FIG. 5 provides only anillustration of one implementation and does not imply any limitationswith regard to the environments in which different embodiments may beimplemented. Many modifications to the depicted environment may be made.

Computing device-luggage 120 includes communications fabric 502, whichprovides communications between cache 516, memory 506, persistentstorage 508, communications unit 510, and input/output (I/O)interface(s) 512. Communications fabric 502 can be implemented with anyarchitecture designed for passing data and/or control informationbetween processors (such as microprocessors, communications and networkprocessors, etc.), system memory, peripheral devices, and any otherhardware components within a system. For example, communications fabric502 can be implemented with one or more buses or a crossbar switch.

Memory 506 and persistent storage 508 are computer readable storagemedia. In this embodiment, memory 506 includes random access memory(RAM). In general, memory 506 can include any suitable volatile ornon-volatile computer readable storage media. Cache 516 is a fast memorythat enhances the performance of computer processor(s) 504 by holdingrecently accessed data, and data near accessed data, from memory 506.

List database 140, luggage contents program 150, initial packingfunction 160, multiple luggage items function 165, and return packingfunction 170 may be stored in persistent storage 508 and in memory 506for execution and/or access by one or more of the respective computerprocessors 504 via cache 516. In an embodiment, persistent storage 508includes a magnetic hard disk drive. Alternatively, or in addition to amagnetic hard disk drive, persistent storage 508 can include a solidstate hard drive, a semiconductor storage device, read-only memory(ROM), erasable programmable read-only memory (EPROM), flash memory, orany other computer readable storage media that is capable of storingprogram instructions or digital information.

The media used by persistent storage 508 may also be removable. Forexample, a removable hard drive may be used for persistent storage 508.Other examples include optical and magnetic disks, thumb drives, andsmart cards that are inserted into a drive for transfer onto anothercomputer readable storage medium that is also part of persistent storage508.

Communications unit 510, in these examples, provides for communicationswith other data processing systems or devices. In these examples,communications unit 510 includes one or more network interface cards.Communications unit 510 may provide communications through the use ofeither or both physical and wireless communications links. List database140, luggage contents program 150, initial packing function 160,multiple luggage items function 165, and return packing function 170 maybe downloaded to persistent storage 508 through communications unit 510.

I/O interface(s) 512 allows for input and output of data with otherdevices that may be connected to server computer 102.
